PUMP.

SPECIFICATION forming part of Letters Patent N 0. 705,670, dated July 29, 1902.

Application filed March 21,

To all whom) Mining/concern Be it known that L I-I NRY T. Hanson, a citizen of the United States, residing at Attica, in the county of Harper and State of Kansas, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention relates to pumps, and more especially to that class known as doubleacting force pumps adapted for submersion in a well, cistern," or other body of water; and my object is to'produce apumpof this character having vertical discharge-pipes wherein the columns of water balance each other, so as to enable a pump submerged at a great depth to be operated by an expenditure of power no greater than a similar pump only slightly submerged and having shorter discharge-pipes. j T

A further object is to produce a pump of the type mentioned which is simple, strong, durable, and cheap of construction and which can be easily and expeditiously secured in'or removed from position.

To these ends the invention consists in certain novel and peculiar features of construction and combinations of parts hereinafter described and claimed; and in order that it may be fully understood reference is ,to be had to the accompanying drawings, in which- Figure 1 isa vertical section of the pump embodying my invention. section taken through the valve connections at the lower end of each discharge-pipe. Fig. 3 is an enlarged cross-section of the pumpcylinder and its valved couplings.

In the said drawings, where like reference characters refer to corresponding parts, 1 designates a suitable frame or frames submerged and secured in a body of water, such as a well, as shown, and 2 a horizontal shaft secured rigidly in said frame or frames and provided with a depending arm 3, having a packing-strip i in its lower edge.

5 designates a cylinder concentrically surrounding shaft 2 and having its inner side engaging frictionally the packing-strip 4 and forming a water-tight joint therewith. Said shaft-arm 3 thus forms a radial partition between "the shaft and the cylinder, a second Fig. 2 is a vertical- 1992.. Serial No. 99,336. (No model.)

, radial partition 6 being integrally formed with the cylinder and having a packing-strip 7, bearing frictionally upon and forming a water-tight joint with said shaft, the heads 8 of the cylinder being secured thereto by side bolts 9 or in any other suitable manner and journaled on the shaft near its ends, the usual stuffing-boxes (not shown) being provided to make the journal water-tight. When the cylinder is at rest, partition or piston 6 is vertically over the" stationary partition or arm 3, and short pipes 10, secured in the cyl inder at equal distances from the piston, are somewhat below the axis of the cylinder. Connected to pipes 10 are T-oouplings 11,

having depending pipes 12, provided with valve-seats 13 for sliding check-valves 14, said check-valves having grooved stems 15 and limited as to upward movement by pins 16, the arrangement being such that water can pass up through pipes 12' and after unseating valves 14: pass through their grooved stems into couplings 11, thence passing through pipes 10 into the cylinder in a mannerhereinafter explained.

17 designates T-pipes, having their stems 18 secured in the upper ends of couplings 11 and provided with valve-seats 19, sliding check-valves 20 of thetype previously described being arranged to unseat under pressure and permit water to pass through the cylinder up through stems 18 and in opposite directions through the heads of said stems, as hereinafter explained.

The T-shaped pipes 17 have their heads journaled in sleeves 21, rigidly connected together, as at 22, and secured upon the ends of said sleeves and forming continuations of the heads of the T-shaped pipes are stuffingboxes 23, these boxes being connected by suitable pipe connections 24: to inverted-T couplings 25, said couplings being secured to the lower ends of and communicating with the vertical discharge-pipes 2 6. Pipes 26 have pin-and-slot connections, as at 27, with and are simultaneously reciprocated in opposite directions by a lever28, which extends transversely of the cylinder and is fulcru med upon a standard 29, mounted on a well cover or' platform 30, through the openings 31 of which said pipes extend, said openings being partially formed by annular walls 32, projecting upward from the platform and having slots 33, for a purpose which hereinafter appears.

34 designates a suitable housing mounted upon the cover or platform and incasing not only the upper portions of the pipes, but also all of the lever except its handle, the lever working through a vertical slot 35 in said housing. The upper part of the housing is in the form of a chamber 36, having a discharge-spout 37 and bottom openings 38,

through which the pipes extend, said open ings being partially formed by upwardly-projecting annular walls 39, having slots 40, in which reciprocate horizontally the plates 41, mounted slidingly on the pipes. These plates are intended to prevent the escape of water from chamber 36 except through the proper channelviz., the spout 37. Similar sliding plates 42 are mounted in slots 33 of walls 32, though these plates may obviously be dispensed with.

The operation of lever 28 causes the cylinder to rock upon shaft 2, which movement is necessarily accompanied by lateral as well as vertical movement of pipes 26, though it will be apparent that by locating the pivotal points of connection between said pipes and T-pipes 17, rigidly supported from the cylinder in alinement with the axis of the cylinder, and by having the lever parallel with such alinement the parallelism of the pipes is never destroyed. They thus move laterallytogether and while sliding through plates 41 and 42 incidentally reciprocate said plates in the slots of their respective Walls. As the cylinder is rotated in one direction its arm or piston 6 moves with it, and thereby synchronously decreases the size of the pistonchamber at one side of stationary arm or partition 3 and increases the size of the opposite chamber. The result is water enters the chamber of increasing capacity and is forced out of the other chamber and into its communicating coupling 11, the lower valve 14 of which closes under this internal pressure and thus compels the water displaced from said chamber to unseat the upper valve 20 and pass up through the T-pipe, pipe connections 24, and pipe 26, escaping thence into the chamber 36 and through the discharge-spout of the latter. As this stroke of the cylinder terminates its movement is in stantly reversed by the reverse movement of the lever. The contracted piston-chamber now expands and the opposite chamber contracts. As the first-named chamber expands it instantly ceases to expel water and permits that which is contained in its connected pipe 26 to close valve 20, the lower valve 14 at the same time opening to admit water into such expanding chamber. The formerlyexpanded and now contracted chamber at the same time expels its water through its respective pipe 26 in the manner above explained. As all subsequent operations are repetitions of those described, it is deemed unnecessary to pursue the description any farther than to direct attention to the fact that as the pipes 26 always stand full of water they balance each other.

From the above description it will be apparent that I have produced a pump which embodies the features of advantage enumerated as desirable in the statement of invention and that the structure is susceptible of modification in some particulars without departing from the scope of the appended claims.

Having thus described the invention, what I claim as new,.and desire to secure by Letters Patent, is
